Grouping many small Goodwill donations into a single entry

I make donations to Goodwill about once a month. Nothing I donate is worth a lot, so I guess the total value for each box of stuff I donate. The total estimated value of all my donations in 2024 was about $400. TT seems to want me to enter dates and descriptions for every donation I made, and I don't want to do that. I just want to enter $400 on line 12 of Schedule A and be done with it. If the IRS wants to audit me, we can go through my receipts then.

 

When I enter $400 on line 12 of Schedule A in TT, it takes it, but the value and the box are in red, and the $400 is not included in the total on line 14. I don't care about the red text or box, but I do care about the fact that the $400 is not included on line 14. How can I get TT to let me lump all my Goodwill donations together and add their total value to line 14 of Schedule A?
