Form 4562 from 2019 transfer to 2020 gives an error

When going through the check process at the end of TT I get an error on line 24 of my Federal Carryover worksheet.  The number that appears on line 24 of my 2020 worksheet is the exact same number that is shown on my form 4562 line 13 (Carryover or disallowed deduction to 2020) that appears on my 2019 return.  What do I need to fix or check?  Totally confused.  I "assume" that the number appears on my line 24 2020 worksheet as a direct carryover by the software from my 2019 return.   Did the number come from somewhere else?  TT says that the total section 179 carryover shown here does not match the sum of the section 179  carryovers on the individual activities so they add up to the total here.  This explanation makes no sense to me.  What am I missing?

 

Thanks in advance for any advice and help!
