My mother-in-law passed away January of 2021. She was 80. I was a beneficiary of her IRA. I neglected to take the RMD for 2021 ($360). My taxes are already filed.

We called the company for her IRA and they issued me the 2021 RMD a couple weeks ago which obviously has this years date of issue.
Im not sure what I need to do if anything at this point since our taxes have already been filed.
