Audit Defense

Hello,
 
I have not finalized my tax return. Nevertheless, I chose to register for Audit Defense because Turbotax sent a notice advising that I must complete registration before April 30, 2025. I get Audit Defense for free with my Turbotax Advantage subscription.
 
I may have some changes to my tax return before I submit it to the IRS in mid-June 2025. Will this Audit Defense also cover the final tax return? If not, must I buy Audit Defense again?
