Reopen my 2024 partnership return

Hi, I filed my 2024 Federal and Connecticut partnership (Form 1065 / CT-1065) returns through TurboTax Business online. I now need to amend the return, but I never purchased the desktop version and therefore don’t have an activation code.
Could you please help me reopen my 2024 partnership return in the hosted environment or provide a way for me to amend it online?
