Looks like they are flat tax rate of 3.23% and here is the link to their dept. of revenue website on estimated tax payments. https://www.in.gov/dor/individual-income-taxes/payments-and-billing/estimated-tax/
Signing off for the day but will check later this evening if you have any other questions.
Have a great evening!!
