Thanks for the reply. The post you referenced contains a link back to another post, similar to mine, which is followed by 10 pages of people dealing with frustrations with this problem. I think some people were able to find a workaround by using forms view and manually making some adjustments. With the online version, which I am using, there is no access to forms view.
The problem is that when you put in the appropriate amount to determine eligibility for an optional deferral on SE tax payments, the program automatically selects the deferral for you. I'd rather pay my 2020 taxes now, rather than next year or the year after.
I believe that Irene above is pointing me to the right solution, but a glitch is not allowing me choose not to take the deferral.
Thanks again!
