Can I have wages and self-employment income from the same $'s

Please let me know if this answers your question, or go into a little more detail.  I will be glad to assist further.

$8400 was listed as housing on my W-2 from a church.  $12,000 was listed on a 1099-R from a retirement fund.

The $8400 on W-2 was listed in box 14 other.  The 1099-R listed $12,000 in box 1 gross distributions.  The W-2 was from a church, 1099-R was from a retirement fund.

I cannot figure how Turbo Tax got $28,800 on Sch SE Adj Work.  It's like $8400 was a double entry.  If I override, the program will not let me e-File.

If the 28,800 was listed on a W2 then it should be listed under wages.  If it is on a 1099 then it should be under self-employment, but not both.
