H1B DS-160 form (with 2 approved I797 starting one after the other)

Hello, I am planning to travel to India in July/August returning before September 1. I have 2 approved I797 notices, one expiring end of Sep 2022 and the other one starting October 1, 2022 for 3 years. Which one should I use for DS-160 form and how can I get visa stamp until 2025? Please advise.

Use the extended I-797 approval # in DS-160 however submit copy of both current and extended to dropbox along with other documents.

Thank you. I will use my new I797 then.
