I wasn't able to print out my city tax return when it popped up and now I can't find it.
Your city tax return will be included with your tax return. Here's how to print the return filed using TurboTax Online:
Sign into your Online account.
Go to My TurboTax on the top left.
Then select My Tax Timeline.
Scroll down to Some Things You Can Do and select Download All forms and worksheets.
Your return will open in Adobe Reader. Click the "printer" icon to open the Print window (or select Print from the File menu in the upper left corner).
