Issue found on 2019 Return

Somehow I accidentally claimed single and TurboTax used the 12k standard deduction on my 2019 return.  I swear I checked the box that said I can be claimed on another's tax return, however I was having connection issues at the time and kept having to go back and redo certain sections online.

Now my parents are getting rejections on their E-File returns as they can't claim me as a dependent.  Is this something that can be corrected when Turbotax releases the 1040X on 2/20?

I should have known there was an issue when the software made me pay the 86.00 fee when it should have been free.  (unless there is an income limit)
