I'm glad to hear you able to file.
For future reference, save copies of your tax documents. Any that are not in a digital format, scan them. Burn all of them to a disk and/or a flash drive, and put a copy on a Cloud drive. I know it's being redundant but disk break, flash drives get lost or reformatted and we replace our computers more often than we'd like.
If the IRS wants to audit you they usually only go back 3 years, but if they find some major errors, they can go back 10 years. Anything beyond that is outside of the statutory limits.
I have religiously used Turbo Tax for many years because I really like being able to import darn near every thing needed.
