Discrepancy between paper and TT itemized deduction total

I filed a paper 1040 return that per USPS was delivered to IRS on 2/19/22.  Unfortunately, after 40 years without problems this return was never processed.  The IRS initially said wait 6 months and don't re-file but in the last month finally said to re-file electronically since there still is no status posted for my refund.  The problem is that my itemized deduction total is different than Turbo Taxes' and I can't understand how that can be.  All I itemize is state tax, property tax, mortgage interest, and charitable contributions.  So that's four figures to add up (even I can do that!).  But what they show for my itemized deduction total is $469 more than what I have.  That would be great as it would mean a slightly bigger refund but I'm fearful that I entered something wrong because it absolutely makes no sense.   The property tax, mortgage interest and charitable contributions amounts on TT all match my paper return. It's the state tax deduction section of TT where the problem lies.  I'm nervous to file until I understand why.
