[Indiana] How can we satisfy work req through capital gains (e.g. selling stocks)?

Hello, I'm currently getting medicaid in Indiana. I understand that any taxable income of $580/month can be used to satisfy the 2027 work requirement. I'm planning to either sell stocks or do traditional to Roth rollover to generate this income.

My question is, what proof do we provide to show that profit has been made? Do we simply take a screenshot of the brokerage website? It looks like Fidelity doesn't generate any monthly document, only tax documents yearly.
