All hope may not be lost!
First, if you have a copy of your return from last year, you can just type in the entries you need for this year. There are usually not that many.
Second, if your preparer gave you a pdf of your tax return, that can be read by TT in the input process, not just a tax file from TT. Also you can generally input files from most other tax software [marketed to the public.] Your preparer from last year might also be able to give you a tax file format that TT can accept, but they wouldn't normally do that unless you asked. Of course, the best time to ask is just before you pay them for the doing the return (last spring!)
