Deductions & credits

Again ... if you use the downloaded version ANY of them will work ... the higher the version the more "help/hand holding" is included.  You can always start with the BASIC and if you want to upgrade you can as you go.

If you want to use the online version it would depend on what your return will include ... If the personal residence sale is not taxable & you are not excluding any foreign income then you can use the FREE version.  If you need to exclude foreign income you will need at least the Deluxe.  You can start with the FREE version and if you need to upgrade you can at that time.
