I purchased Turbo Tax Premier, Does it have Form 1040-SR? I am retired and no longer wish to file 1040.

All versions of TurboTax have Form 1040SR.  If you were 65 or older by the end of 2019 then your return will automatically be on the 1040SR.  There is no reason whatsoever to be anxious about whether your return is on a Form 1040 or 1040SR.  The 1040SR has a larger font. All of the lines are the same as Form 1040.  All of the calculations are done exactly the same way.

"Does it have Form 1040-SR?"

Yes, Form 1040-SR is available.
