Thank you @MJoy_D for taking the time to so carefully and clearly repeat the exact same instructions that I said I had followed already - I suppose it never hurts to try the exact same thing for a 10th or 12th time! I think you'll find if you read my post carefully you will see that this is exactly the procedure I followed, although the clearing-cache and incognito-mode trick was at least worth a shot, although it did not help. I suppose that the "Error" that I see in the "types of supported deductions" dropdown is indeed an error, and I suppose I need to get someone from support to look at my specific issue? The entire list of account types I see in that drop down are in my initial post.
