Can I leave Turbo Tax when it shows return in progress and go somewhere else. I have no income just social security so Turbo Tax can't e-file and I can't print it.

Since you aren't required to file and there is no benefit to doing so, why do you want to?

I have in the past and I have to file state with Ohio.

First, to answer your question, you can leave Turbotax if you want to.

But..It is actually possible to efile you return even though you have only Social Security income. You have to enter $1 of other income and label it "to permit efiling".
