What do I type in the “prior year tax” box?

The best place to get last year's AGI is from the 1040 form you filed with the IRS. Look on page 2, line 7. If you filed a 1040NR, it'll be on line 35. For information on ways to obtain your 2018 AGI, please click here.

Help please 🙂  What do you enter in this box? Rhode island income tax? the taxes you paid to rhode island in 2020? I'm filling out a non-resident rhode island tax form.  Thank You!

This screen has to do with the possible underpayment of estimated tax.

Enter the amount from your tax year 2020 Form RI-1040, line 10a less line 14d and 14e, or Form RI-1040NR, line 13a less line 17d.  

See 2021 Form RI-2210A in the RI-1040NR Instructions for more information.
