Can i add the interest from my 2021 taxes on my 2022 taxes if i forgot to do it 

 


No.  Interest for 2021 has to be entered on a 2021 tax return.  You will have to amend the 2021 tax return to add the 2021 interest.

 

See this TurboTax support FAQ for amending a tax return - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/amend-change-correct-return-a...

 

A 2021 amended tax return can only be printed, signed, dated and mailed by you to the IRS, it cannot be e-filed.
