I can't seem to get a copy of my return or save a copy to my documents.

Please see this FAQ on how to get a copy of your tax return:

Or you can try this option:

Please log back in your TurboTax account and "add a state" to open the return back up (you are not really adding a state, just to open it back up), then select Tools on the left, Print Center and choose the print center, then select returns and choose to print just the tax return or to include all worksheets as well.

You did not find this helpful, can I clarify anything?
