H4 to H1 COS query

Hello Members
I have H4 I797A valid till 2025. Meanwhile my H1 COS got approved (H4 to H1). My H1 I797A valid till 2024. I don’t have any of these (H4/H1) visa stamped right now.
Now I m planning to go to India and come back to US on H4.

  1. Can I use my H4 I797A for stamping? Is it invalid as COS (H4 to H1) was approved ?
  2. Or just my spouse’s I797A is sufficient for my H4 stamping?
  3. What documents should I present for my h4 stamping?
    Please share your inputs!
