Paying Employee/Employer Social Security tax with turbotax??

I'm trying to file my daughter's taxes for free via turbotax.  She is a Medical Transcriptionist and is considered to be a business owner rather than just an employee.  This means that she has to pay 100% of the Social Security taxes but turbo tax is only having her pay 50% as an employee.  She received a 1099-NEC which I have indicated in the filing so far.  How do I get the 100% tax paid while using turbo tax?  My daughter is a single parent with two young children and has a very low income.  So far, with turbo tax she's getting a sizeable refund but would rather pay the whole tax debt now rather than have to cough up more money later on when she can't afford it.
