Retirement tax questions

If the IRA owner died prior to January 1, 2020, (in my case March 2017) and a non-spouse Inherited IRA was established: 

1. Am I subject to 10 year rule? (I don't think so.)

2. Was I required to take RMD each year through 2024? (I did, but I do not think I had/have to for 2020-2024)

Thank you.
