Hi! In the system, I am only able to add sales tax for one of the places I lived (Charleston, SC), but I would like to also add it for another place (Sarasota, FL).

If you want the program to "estimate" your sales tax paid, you must use your tax rate. 

If you want to enter sales tax that you paid, including a different state, enter the sales tax amount you calculated using receipts.
