Tax refund amount has changed after updating Turbo Tax

I filed in April 2023. Today, 5/25 I opened Turbo Tax and it asked me to update it. After that I saw the amount of my federal tax refund was different from when I filed. When I exited, it did not ask my to save but when I looked at the timestamp of my file, it was updated to 5/25. How do I get back the copy I had in April? Why is the amount changed? I did not do anything other than update Turbo Tax. Will this be a problem when I file next year coz the amount is not consistent anymore from the amount I filed. Do I need to file an amended return so IRS has this new copy?
