If he has a W-2 with boxes 3-6 blank, you don't need the SE version (unless he has cash side income to report such as from weddings and funerals -- in that case he is acting as an independent contractor for those wages.)
If he has a 1099-MISC or only receives a housing allowance with no income taxable wages or W-2, then you need to use the self-employed version to get the SE taxes on the housing allowance calculated correctly.
So how do I switch versions? and keep all my entered information?
I don't think you can. You can clear and start over but that means clear and start over. Turbotax's view is that once you have upgraded, you are experiencing the benefits of the higher version, and so must pay. (Even if the only "benefit" is finding out you don't need it.)
It has this carryover dollar amount from form 465 I think. I can't get rid of that
If you have a carry over loss from a previous year then I think you need self employed this year even if you are not in business this year. But I need to ask someone else to confirm.
@bwa or @Hal_Al or @TaxGuyBill ??
It seems like it may be a "§465(d)" carryover, which likely means you checked a wrong box LAST YEAR.

As for how to get rid of it, I don't know. If you wrongly checked the 'not at risk' box last year, you could amend last year to use that amount, then when you transfer, it shouldn't transfer that.
