Will I know if the IRS has viewed my return? I e filed 2 days ago and it still says pending. Will it say accepted or denied when they view it? Thanks

as of now your return is sitting on TT servers waiting for the IRS to open e-filing. after TT submits it you'll get either an acceptance or rejection email. look for it. if rejected you can fix and resubmit.    many of the notices sent out by the IRS are automatically generated by its computers without any human ever looking at your return.  simply a matter of the info the IRS has not agreeing with the data on your return. unless you are a billionaire the chances of an actual human at the IRS looking at your return is quite small

It will say Pending until the IRS either accepts or rejects your return which won't be until after they open on Feb 12, 2021. Be patient and watch your emails.  

Even if Turbo Tax lets you submit your return they will just hold all the returns until the IRS opens filing on Feb 12, 2021. So there is no hurry. And a lot of people who file early find out they have to amend later like when they get their actual W2 and 1099 forms. Or they get more forms than they were expecting.

Then after the IRS accepts your return they pay most refunds within 21 days.

The IRS won't open filing until Feb 12, 2021 this year
