Why are you even worried about it?
FORM 1040 and FORM 1040SR
There seems to be a considerable amount of confusion and worry regarding the new Form 1040SR. There is no need to worry if your return is on a Form 1040SR this year.
Compare the Form 1040 and the Form 1040SR with each other. The lines are the same. The calculations will be done exactly the same way. The difference is the 1040SR has larger print and a different background color. There is no effect whatsoever on your tax due or refund amount.
I personally think it is great that I will not need a magnifying glass to look at my tax return this year.
When I buy the Version that I normally use, will using the 1040-SR as an option or do I need to purchase a specific program?
See the answer above your post - in TurboTax that are the same. The 1040SR is only different if you download blank forms and fill then out by hand. The TurboTax interview is the same and will print the 1040SR if you qualify and print for filing. If you e-file then the form type is immaterial since notactual form is sent, only the tax data is.
The 1040SR is new starting in 2019. It is the same as the regular 1040 just larger type and the Standard Deduction chart is added to page 1. But has the same line numbers. You automatically get the SR if you are 65. If you are using the Desktop program there is a way to force the one you want.
Even the regular 2019 1040 return is now different than 2018. They changed the line numbers again and reduced the new schedules from 6 to 3.
If you use the Desktop program you can switch to forms and the Info Wks part II has a selection to select 1040SR or not. You can not change it in the Online versions. In the Online version if you want to use the regular 1040 form, you can print out the 1040SR and copy the amounts onto the 1040 and then mail your return.

don't misplace your magnifying glass since all the other attached Forms and Schedules are in the same font size as ever.
It's quite ridiculous.
