Forgot to report 401k contribution? From 1099-R

Dear Community,

 

Basic noob question, I noticed i did not include my prior year's 1099-R form, the 2a Taxable amount shows $0 and Distribution Code is G (rollover).  The "IRA/SEP/SIMPLE" box is NOT checked.

 

Explanation:

Distribution code G on your 1099-R indicates that your WRS benefit was rolled over to another qualified plan

 

I try to enter them in Turbotax and still does not reflect any tax changes (not due nor refund)

 

Question:

Given it was 2 years ago, does it make sense to amend everything, including tax 2020, tax 2021?

 

Thanks
