OK, I think I have figured things out a little more. I think Turbotax is correct in that it is not adding additional SS tax to my wife's SE income.
That said, I am not allowed to go into Schedule 3 Line 11 and ask for a credit for the 140 dollars overwithheld. At least, I haven't been able to find it either under the guided section and even when I go into forms themselves, Turbotax for some reason isn't allowing me to manually add this in.
Looking at other comments, it would appear that the IRS and Turbotax are now disallowing this workaround process and is instead asking for corrected W2s and refunds to be issued by the employer even though my wife's employers have separate EINs? If so then why even have this line on the tax form asking for overwithheld SS amounts?
