I am the sole beneficiary of an Inherited IRA in a Trust with my late mother's name. How do I declare the RMD?

I have a feeling, from reading @dmertz replies to other related questions, that it is the estate that pays the taxes and that the payments to me from the estate are not taxable because it is an inheritance?

 

I assumed I needed to report the income and include a K-1 issued by the trust.

 

I have been trying to figure out what line on the K-1 form to report the income for the Trust to give me. 

 

My brother (the fiduciary) sent me  the Required Min Distribution from mom's IRA.  We didn't have to deal with this the year she died because it was 2020 and there was no RMD that year for anyone.  But now I'm having to figure this out.  

 

He sent me a check from the IRA in 2021.

 

Thank you for guidance.  I do have the business level of TurboTax.
