Retirement tax questions

For 2020 and 2021 American Funds sent me a single 1099-R but showed separate rows for the multiple funds I received distributions from. My confusion when completing taxes is that each fund has a different fund number but turbo tax only has one spot for one fund on each 1099-R template. I'm not sure if I should keep adding additional 1099-Rs for each fund or just add up all the boxes and just pick one of the fund numbers to enter.
