QBI deduction (phased in reduction)

I have QBI that is from an SSTB and my income is within (but not greater than) the phase-out range.  I understand that a portion of my QBI will be reduced, however the Turbo tax software seems to be reducing it twice.  It is first reduced on rows 5 through 11 of the Form 8995A Schedule A Smart Worksheet.  This reduced amount carries to Line 2 of Form 8995-A, where it is subsequently reduced again in Part III of that form.  This does not seem right to me.  I may have input something wrong but I can't figure out where.  Has anyone else seen this?  Is it correct?  Any suggestions?
