I started my taxes in Feb. and paid for Turbotax self employed, but I need to make a change to my return before filing. It won't let me access my return except to print

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.
