I keep getting denied on my TurboTax and now I'm not getting a stimulus checks I'm trying to figure out how I can get accepted through we all this is my third year in a row I believe I've been denied

What do you mean denied?  Did your returns Reject?  Did your prior returns ever get filed?  It is too early to file 2020.  The IRS won't open filing until Jan 27 so you have to wait.

The first Stimulus Check is really based on your 2020 return we are filing in 2021.  So any amount you already got will be reconciled on your 2020 return line 30.  If you didn't get a Stimulus Check (and qualify) or you qualify for more it will be added to your 2020 return.  But the good news is if they paid you too much they won't take it back.

I think the second one will be on your tax return also.  They are still working on updating the program for it.

When you go through the federal review tab it will ask how much you got if any.  Or to enter your stimulus payment in TurboTax, type "stimulus" (without the quotes) in the Search box, then click the link that says "Jump to stimulus."
