Can I safely save my filing now until I get my other tax form?

[LindaA]

Yes, you can save your work by clicking Sign Out in the lower left corner of the TurboTax Online window. TurboTax will save your information before returning you to the sign in screen. When you are ready to return and add your additional information, just sign in, click Take me to my return, then click Pick up where I left off.

Can I save my return and come back later?   https://ttlc.intuit.com/replies/3301211
