Locating Schedule A

I may have possibly deleted Schedule A.  I just started working on tax year 2019, which I downloaded last night.  It was there when I started, but it no longer appears on the left hand side under "Forms in My Return."  I can bring it back up under "Open Forms," but once I leave Turbo Tax (Deluxe), it goes away and I have to bring it up again the next time I use Turbo Tax. How can I save Schedule A so that it remains under "Forms in my Return?"
