Taxes for 2020 why did they file as 2021

[SweetieJean]

TT Online is only good for tax year 2021.

Since you accidentally used your 2020 info instead, you must wait until after Jan 24 to see if the IRS accepts or rejects it.  If rejected, you can simply delete the filing.  If accepted, you will have to do a 1040-X amended return, but using the correct 2021 information. 

In either case, to file 2020, you must purchase and install the 2020 desktop software, and file by mail.

Since you filed 2020 as your 2021 return you still need to file 2020.

To do a prior year return you have to buy the Desktop program here,

You will need a full Windows or Mac to install it on.

If you want to file for free you can fill out the forms by hand. Here are some basic forms…..

Here is the IRS 2020 Form 1040

Sch 3 : https://www.irs.gov/pub/irs-prior/f1040s3--2020.pdf

Then when you do file 2021 enter 0 for the 2020 AGI since you are filing 2020 late.

You have to print and mail prior year returns. When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return. Don’t forget state.

Important! Mail Federal and State in separate envelopes and mail each year in separate envelopes.
