It won’t allow me to use Apple Pay as an option for payment

TurboTax does not accept Apple Pay. We accept all major credit and debit cards, but you can also choose to pay for your TurboTax fees right out of your federal tax refund. There is an additional fee for this service*. 

Then why do you have a giant super prominent Apple Pay button on your app.  You should remove this immediately.

The answer on this post is actually from several years ago.  When the Q&A's were ported over from the prior forum the dates did not transfer, so the date on the Q&A's are the date of the transfer.

Ironically, Apple pay doesn't work this year (2020) either. Just got off the phone with someone from TurboTax who verified I was not alone in having no success with Apple Pay. Double irony? That is the only way to pay on an iPad or iPhone unless you want to pay with your refund (and get charged an extra $50). Get it together Intuit!
