Social Security Over Withholding between 2 W2s and SE income and how to correct

My wife has three sources of income.  Two W2s and a shared sole proprietor business that we split into two Schedule Cs, one for me and one for her.

 

From a single W2 she already hit the cap for Social Security taxes this year, having had 8853.60 withheld.  Her second W2 withheld around 140 dollars for SS.  Turbotax is telling me that I should ask for a refund from her second employer and get an amended W2.  That sounds like a lot of hassle and it seems like I can just ask for a 140 dollar credit on Schedule 3 Line #11.  I'm assuming this is ok.

 

My main issue though is the sole proprietorship.  She has a fair amount of income there on her Schedule C and Turbotax uses a separate Schedule SE for her portion of our business to calculate SE tax.  I know some of it is Medicare, but I'm guessing some of it is additional Social Security tax.  I can't tell how to separate the additional SS tax from her Medicare tax.  If I could figure out her additional SS tax from our sole proprietorship I would ask for that as a credit on Schedule 3 Line #11 as well?

 

Thanks in advance
