Maybe. If you use It's Deductible to import your charitable donations, you can sort your list there first.
If you using TurboTax Desktop, in FORMS mode, you can click on the table heading labeled "Charity Name" , and the whole list gets alphabetized while in that interview section. It isn't permanent though, so once you exit, they get scrambled again, but a simple one-click the next time you get into the charity section, does it again.
Also, in the program, all your cash donations can simply be entered as ONE amount using the word VARIOUS and skip all the individual entries. The IRS only gets the one total amount on the Sch A; the worksheet with the breakdown is only for your records and you already have the receipts in case you are ever audited.
