@SteamTrain Here is a reply from Champ @rjs to the question I posted to the Lounge about Full Service TurboTax Business
There's no such thing as transferring data into Full Service (either business or personal). Full Service Business is not software, it's a service. The return is prepared by a tax pro who is hired by Intuit. I'm pretty sure that the Full Service preparers do not use TurboTax. They use whatever professional software they use for all their clients. It's just like going to a local tax pro, except that you communicate online instead of going in to the preparer's office. So it's unlikely that they would be able to transfer data from a TurboTax Business file. As far as I know, the only professional software that can open a TurboTax file is ProSeries. It can open a TurboTax 1040 file, but I don't know if it can open or transfer a business file (1041, 1065, 1120, or 1120-S). And, of course, being able to open a file is not the same as being able to transfer the data to the following year.
