After you file

Back in 2020 I e-filed using TurboTax. Being a newbie to e-filing, afterwards I found that I neglected to include a 1099-R for about $2400. I estimate the extra taxes to be less than $300 back then.  Naturally it carried over to the state return.Thus far neither the IRS nor the state have caught the error.

 

If I decide to amend my returns

 

#1  is there a fee to file amended returns?

#2  Will the right numbers end up in the right spaces as these amended returns can sometimes be confusing? Will taxable Social Security be recalculated?

#3  How likely is it that I will have to mail in paper returns along with a check rather than debit from a bank account?

#4  We have IP PINS so would I use the ones from 2020 or the current ones?

#5  Is there a statute of limitations for errors like this?

 

I think that that's it for now.
