How to correct Tax year Beginning Date

I started an LLC part way through 2019 and initially I entered the wrong date (6/28/2019), under Business Info, as the "Date you stared doing business." The issue is I later corrected this date to 5/21/2019, but my 1065 and all other documents still reflect the initial incorrect date (6/28/2019). 

 

I already e-filed when I found the tax year beginning date was still incorrect (shows 6/28/2019 and should be 5/21/2019), even though I corrected it. Do I need to submit a revised return. If yes, how do I correct the Tax Year Beginning Date? 

 

Also I already started the process to revise my return, but I do not see anyway to revise the Tax Year Beginning Date, because the "Date you started doing business" already reflects the correct date of 5/21/2019, but all my return forms still incorrectly show 6/28/2019. Any help would be greatly appreciated.
