We already claimed The American Opportunity Tax Credit for our daughter the previous 4 tax years. How do I amend our Federal tax return to correct the number of years?

If you are saying that you filed your 2023 return and claimed the American Opportunity Tax Credit for a fifth year for your daughter and you need to amend it, then you will be changing the answers in the Education Credit section of your return.  When you indicate that you have already claimed the American Opportunity Tax Credit for four previous years, then your education expenses will be considered for the Lifetime Learning Credit.
