Form 2210A requires Quarterly amounts for Lines A,B & D, yet the 1099 from the financial institution does not list quarterly amounts.and is unaware of this reporting need
You have to make your best guess how much of that 1099 is applicable to those periods, inclusive: 1/1 to 3/31, 5/31/, 8/31. If you have monthly statements then you can figure it out from those.
