Turbo Tax Business 2021 M-2 Calculation error

I have my M-1 in balance without overwriting any values.  However, the M-2 does not seem to be bringing down the proper book value for line 3.  The M-1 was able to reconcile this value properly on Line 1.  On the M-2 worksheet section in Forms mode, it is only pulling in my non-deductible values and disregards the depreciation difference between books and taxes.  Is this correct?  Should not the M-2 Line 3 value be pulled from the M-1 Line 1?
