The special amend software is complimentary at the link SuperUser macuser_22. You won't have to purchase anything.
By the way, what TurboTax product did you use for your return? It says "Free Edition" by your username above. Is that correct? To deduct state and local sales tax, one would have needed to use Deluxe or higher, AND one would need to be able to use itemized deductions on Schedule A. i.e., Do the state and local sales taxes plus all your other itemized deductions (medical, charity, property taxes, interest, 2% misc. deductions, etc.) exceed your standard deduction?
