amending 1065 return to categorize partnership as passive

I did my first 1065 partnership tax return for 2020 on TurboTax.  Unfortunately, after discussing with my CPA today, I found out that I categorized the partners incorrectly.  Since my LLC is a holding company, therefore, it's passive, I was supposed to check the boxes that state that the partners are passive LLC members & not ACTIVE managers.  Therefore, on my 2020 1065, it showed a self-employment loss (income) in box 14 when, technically, there shouldn't be anything there since my LLC is a passive entity.  I tried to go back in to TurboTax Business 2020 to amend the return but it didn't allow me to change the partnership selection.

 

How do I do/fix this?

 

Thank you.
