Marriage and 1098-T

Yes, it is possible that changing your name with Social Security may have delayed your refund.  The name on your tax return needs to match the name on your Social Security card.  Since you have yet to receive your refund your best option is to call the IRS at 1-800-829-1040 to understand what the issue is.

Hi, I got married February 3rd, 2020, but I filed my taxes in January, so I filed single.

What changes occurred in your life in 2020 has absolutely no bearing in any way, form or fashion on your 2019 taxes. If you were not married on or before Dec 31 2019, then you had "NO CHOICE" but to file your 2019 tax return with a filing status of single.

I did not work and I only filed my 1098-T.

So how did you support yourself in 2019? Sounds to me like you're an undergraduate that was under the age of 24 on Dec 31 2019. That means your parents qualify to claim you as a dependent on their 2019 tax return. Then it would be your parents (not you) that would report all the education stuff on their tax return.

I was qualified to receive some money back.

I don't see how you can be getting anything back from the IRS, since you didn't pay any taxes at all in 2019.  But then, without knowing "the whole picture" for your specific and explicit situation in 2019, there are apparently things I'm not aware of. So I can't and won't refute your above comment.

However, I changed my last name with the SSA on the 13th.

The 13th of Jan or Feb in 2020? No effect on your 2019 stuff, since the IRS pulled all the data they need from the SSA computers before Dec 31 of 2019.

My refund is still processing and I’m not sure if me doing this has delayed my return for 2019 or not.

If you filed as single (which would be correct) and used your married last name (I assume your last name changed after marriage) then yes, that will create a delay.  No doubt about it. All you can do is wait.

It says I was supposed to receive it around February 20th, but I have yet to receive it. I’m confused on what is going on.

At this point, no news is good news. You can check the status directly with the IRS at https://www.irs.gov/refunds.

If things are delayed, I suspect it's for one or more of several reasons.

 - You incorrectly reported to the IRS that you do not qualify to be claimed as a dependent on your parent's tax return (when in fact, you do qualify as your parent's dependent in 2019)

 - You incorrectly claimed a credit you do not qualify for, because you incorrectly claimed your parents do not qualify to claim you

- You used your married name on your 2019 return. That will create a delay in  your case, while the IRS confirms this is "in fact" your name now. If receiving a refund, then you were correct to use your married name on the 2019 return, so that the refund check will be accepted by the bank. If you receive a paper check, that needs to have your married name on it, so you can cash it. If you elected direct deposit, then the name(s) on the tax return *must* match the name(s) on the account it will be credited to. If any one name doesn't match, the bank will reject it back to the IRS.

For either of the above, if the IRS is questioning anything you can expect to receive a letter from the IRS in the mail about 6-8 weeks after the IRS computers have accepted to your e-filed return.

Bottom line is, you have no choice but to wait. Meanwhile, you can check the status at the aforementioned website to see what the IRS has at this moment in time.
