I need to save a file of my submitted return so I can find info from specific filing lines like 1500 nor 2300 etc.

How can I get my turbotax software to do this

Sign into TurboTax Online, and then scroll to the bottom of the page. There you'll find a list of all the returns previously filed using the account you signed into, and you can download a PDF with all the tax return forms.
