Retirement tax questions

Thanks for your clear answer.

 

Just double checking here....when I start withdrawing RMDs from my IRAs, the inherited non-spousal IRA is not aggregated with my IRAs to figure the RMD from my own IRAs?  I am already collecting the RMD yearly for the inherited IRA.  I also have a 401K with a former employer, can you verify that its RMD is calculated separately from the IRAs (think I read that someplace).
