Missed reporting interest payment in previous year's (2020) tax return ?

Hi,

I just realized that I missed reporting interest income of $61 in my 2020 tax return which I filed last year. I got no inquiry from IRS about the mismatch and online portal shows my return was accepted.

Now, do I need to do anything about it OR is it just accepted ?

 

I asked turbo tax on-call support and h&r block support, both are giving different answers:

- One said that I can simply report that $61 income in my 2021 tax return

- Other said I need to file an amendment for my 2020 tax return.

 

What is the correct way to handle this ?

 

Is there any IRS documentation online which covers specifically such a scenario ?
