Can I pay to have a turbo tax expert do an amendment form even if I didn’t file through turbo tax?

It appears as if the service is still available.

Doing an amendment to taxes not filed with TurboTax would be outside the scope of the expert tax preparation team.  You should use the software or person who did your original return to do the amendment.
