Filing another amended return for IRS 2024

I amended 2024 return to add my daughter as dependent which was inadvertently left off original return. IRS reviewed amended return, and I received a letter back from IRS stating that I need to amend the return AGAIN and include Form 8863 claiming the Lifetime Learning Credit instead of the American Opportunity Tax Credit. In addition, I am to "subtract" tax free scholarship in order to properly calculate qualifying education expenses.

So, my questions are as follows:

1. How many times can I amend IRS taxes using 2024 TurboTax program on my computer?

2. Will the program recognize I'm amending the taxes again and override the 1st amended documents?

3. Should I save the new amended forms under a different name like "Amended taxes #2"?

4. Lastly, where do I subtract the "tax free scholarship" and from what?

Thank you
