Great! Thanks, this helped me get my amended return filed. Yeah my research also showed that starting in 2022 you can amend your Indiana return using IT-40 with the box checked.
See reference:

Turbo tax fills all the info in for you on the PDF, so all you have to do is print it out, and attach any required documents and payment.
