@dmertz thanks for the answer, but just to clarify, I use the "Home and Business" edition of turbotax.
On tab Personal I entered my W2 (Box 12AA = $20,500 for the Roth)
On tab Business I entered all my business info, including Self-Employed retirement. Under Individual 401K Elective Deferral I entered $4,000.
Why turbo tax did not give me a warning saying that my total elective contribution was over the limit? It has all the data (Roth from personal + elective deferral).
If Turbo Tax had given me the warning this would help me realize the I should not enter the 4000 as elective deferral (since it is after tax).
Does that make sense?
