How do I modify return in turbotax that was not yet sent to IRS? (I did not file through turbotax...only saved paper/pdf copy)

Please see the instructions below on how to open your return for editing:

• In TurboTax Online, sign into your account.
• Select Tax Home in the left menu.
• Scroll down to Your tax returns & documents.
• Select 2018, and then select Add a State (you're not actually adding a state, this just gets you into the right menu).
• You should now see the Tax Timeline, select any heading to begin editing.
