Allow me to chime in, @lax1.
If you don't have the option to select the drop-downs under tax payment, I suggest checking to make sure you're using an admin login. This will ensure you have access to make the changes to your tax payments. If you're logged in to an admin account, then you'll want to open the program in a private window. The program will then run without collecting browsing data. After you delete the payments, you'll want to clear your cache and cookies to ensure your web browser runs more smoothly.
Feel free to comment below if you have any other questions. I'm always here to help.
