Thank you for your questions, my friend
You are required to get the RMD - Required Minimun distribution from the following accounts:
- Pensions
- Profit-Sharing
- 401(k)
- 403(b)
- 457(B)
- Simple IRA's
You are not required to take RMD from Roth IRA's.
You have to calculate your RMD separately for each of your accounts plans.
Normally, you are responsible to calculate the RMD but in many cases your financial institution will calculate the RMD. If you want to calculated yourself you can use the following publication 590-B at https://www.irs.gov/pub/irs-pdf/p590b.pdf.

I hope I was able to answered your questions
Thank you so much
