Turbo tax is confusing. My pension is totally different from the fund I'm required tp take the RMD from, but it doesn't separate it in Turbo tax.

If you are age 70 1/2 or older in 2019 and you receive pension income from a former employer reported on a Form 1099-R, then all of that income is an RMD.

all you have to do is key in the 1099R form into TT.   

Some firms (Vanguard is one) will provide the detail of each fund they sold in order to effect the RMD.  That detail is not required as part of the tax return.  Again, just key the 1099R and not worry about what funds were sold to create the RMD
