You would find the social security entry screen in the Wages and Income section, then Retirement Plans and Social Security, then Social Security (1099-SSA, RRB-1099).
Go to Federal> Wages & Income>>Retirement Plans and Social Security (SSA1099 and 1099RRB) to enter your SSA1099.
That is exactly what I did per the step-by-step instructions as well as manual selection as you described. However, what I got was a blank page with no form. I was left in that state forever. Exited back to the beginning of the step-by-step procedure with the same result. This also happened last year with the Deluxe version of Turbo Tax as well. I have used premier version of Turbo Tax in the past, which properly presented the (1099-SSA, RRB-1099) entry forms for the step-by-step process. The deluxe version of Turbo Tax is broken. This is for a windows 10 system.
See my previous reply to ThomasM125. The only way I could make the SS entries was to directly access Social Security (SSA1099 and 1099RRB0) forms in the forms view instead of in the step-by-step process. Some users may not know how to do that, if they are used to using the step-by-step process. They my even miss making the entry for SS.
