Absolutely, you need to always check the exact entries for your withholding for any forms you entered to make sure they are exactly correct. Sometimes people invert two numbers, or double-hit a key, and TTX only uses what you entered or imported (and occasionally, even some imports are mis-formatted at the issuer end), and can't know if you entered some numbers wrongly.
________________
One thing to note, is that if you received and entered any 1099-R forms, some suppliers issued 1099-R forms for 2020 with the boxes mis-numbered (using old 2019 formatting instead of proper IRS approved 2020 numbering). So it is critical that you make sure you put the withholding $$ in the proper 2020 boxes in the software forms, down in the state section of the software forms.
