Sorry, the only copy was on your computer or any removable back up devices you used.

Unfortunately, no. THe only place the partnership return form 1065 exists is on your computer. If you didn't make a backup, then its lost and you'll have to enter everything manually. Hopefully you have a printout or PDF file of the 1065 to work from. Otherwise, you'll have to get it from the IRS which will take a few weeks.
