I had a typo in my earlier reply, it should have said, "If the $19,000 is reported in box 12 of a W-2 ..." Some self-employed also have another employer and make 401(k) contributions there. It's quite common for people to mistake a 401(k) for an IRA and try to enter their 401(k) contributions as IRA contributions.
Exactly what is the error message you are seeing?
