I had an issue on my state returns, and had to make an amended return. These documents are not showing in my account or documents and I need to reference them.

Please try this printing 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.
