Withdrawal from Roth that I've had for 30 years

I've had a Roth IRA for 30 years and have never taken any money out of it.  Last year (2023) I withdrew $55,000.  I'm trying to do my taxes.  Turbo Tax asks me if I've had the Roth for over 5 years.  I answer yes. The it asks me for the contributions I made prior to 2023.  The problem is I have never kept track of the contributions.  I haven't contributed any money to my Roth IRA since 2014 when I retired.  How do I answer this question?  Do I just guess?
