Yes, I advise you file an extension until you have this form.
Here is how:
- Open your return in TurboTax Online.
(To do this, sign in to TurboTax and select the Take me to my return button.)
- Select File an extension at the bottom of the column on the left side of the screen.
- If you don't see the File an extension button in Step 2 above, search for extend in the upper right and select the Jump to link at the top of your search results.
- Follow the onscreen instructions to e-file your extension.
