Can I fund a ROTH IRA with Foreign income? If so, how do enter it without getting the foreign exemption/credit? I want to pay for my contribution and that's it

I'm trying to input just the amount my husband and I contribute to a ROTH with foreign income.  The rest of the income I want to be exempt.  I can't find a way to do this with this software.  HR Block were absolutely no help.  Told me to talk to a software designer
