Forgot to add 1099-R info in 2020 Tax Return. Need to Amend?

Hi,

 

I have a 1099-R form that I forgot to file with my 2020 tax return, which my employer 401k traditional after-tax contributions were automatically converted to Roth 401k contributions. Box 2a (taxable amount) was $0.03 and box 4 was $0.00. Box 7 is G. 

 

Do I need to amend my 2020 tax returns?

 

Thanks in advanced.
