Backdoor roth and SEP IRA balance - how to report on Form 8606

I contributed $650 (hypothetical) into my SEP IRA in 2024 and did a backdoor roth conversion of $7000 in 2024. As of Dec 31, 2024, I had about $700 balance in my SEP IRA. Due to this balance, it seems that part of the $7000 roth conversion is now taxable due to the pro rata rule? I have the Windows desktop Home & Business version of Turbotax, how do I trigger Form 8606 and report the roth conversion as well as the pro-rated portion that is taxable?
