Just choose the standard, plain old 1099-R
Don't know what the Online software asks, but the desktop version has text that indicates the standard 1099-R is for "money from 401(k) retirement plans, pensions, IRAs, etc."
....as it should.
But not US Govt pensions from OPM (except TSP accounts), nor RR Retirements or Social Security, which are different forms.
