Itemized Deductions

We've filed our business/family taxes with TT for over 20 years. All of a sudden, THIS year, TT is INSISTING that we filed the standard deduction, not itemized, last year.  This is wrong. We have ALWAYS itemized deductions.  Now the software is insisting the I give them information from tax forms (like Form 2 or Schedule A) that we DO NOT HAVE for 2018 because we have a Schedule C, because of the business.  It is now asking for information from our 1040 that doesn't make sense. The lines don't match up with what they're asking (like line 14 on our form is "other taxes" and the software insists that line 14 is "taxes after credits".  It is not.)  Help, please.  I'm now stuck.  I don't know WHY it would think we EVER took the standard deduction and why it cares.
