Amending a 2021 Return

[Once a year Accountant]

As fate would have it --- in doing my 2022 taxes I found a mistake that I made on my 2021 taxes (not in my favor of course -- so I get to pay more money to the government).

My question is I still have Turbo Tax 2021 on my desktop so I did an Amendment to my 2021 return and what I owe. 

My question is --- isn't their some type of penalty I am also going to be hit with since it has been over a year.  I am so mad -- it was a stupid mistake I accidentally entered 1098 info in two places.  

Thank you for any help, advice !!

Yes, you will be assessed a penalty and interest on the amount of additional tax you owe.  The IRS will calculate it and bill you once they have processed your amended return.

Amendment to a 2021 Return :(

Hi --- as fate would have it when I was doing my 2022 Taxes I found a mistake I made last year on my 2021 taxes.  And of course it is not in my favor.  :(  I have a few questions.

1)  Can I go back to Turbo Tax 2021 (which I still have loaded on my computer) to fix/Amend the return?  Or do I need to do it all in Turbo Tax 2022 ?

2)   At this point I used Turbo Tax 2021 to fix/Amend my 2021 Tax return.  Assuming that I can use Turbo Tax 2021 to Amend my return ... can I use Turbo Tax 2021 to eFile it ?  Or do I need to do via paper/Mail  ?

3) Seeing that I just found this Mistake when doing  my 2022 taxes ...... isn't  there a penalty that I need to add on since it is a year after the fact ?  if so How do I determine the Penalty ?  Turbo Tax did not tell me the penalty fee ?

Thank you

Yes, you use the 2021 TurboTax desktop program to amend the 2021 tax return. 

No, the amended return cannot be e-filed it must be printed and mailed to the IRS.

If there are taxes owed on the amended return, you pay the taxes owed.  After the taxes are paid the IRS will send you a bill in the mail for any penalties and interest.

Follow on ---- The error I made in my Federal has NO-Impact on my State taxes when I when through them again in Turbo Tax --- do I still need to send in a CT Amended return  that shows No balance due and No balance owed ?
