Your best bet is to call customer support on Monday morning. You can pay by phone using a credit card. If you only have cash, the easiest thing is probably to go to a grocery or drug store and use that cash to buy a preloaded credit card or Visa or MasterCard gift card. (They may be able to debit from your bank account with a verbal authorization, but I'm not sure.)
For customer support hours and link, see below. Use the web form and type your question or a keyword. You will get an appropriate phone number for your issue. (You will not get a phone number if you use the link outside of operating hours.) https://ttlc.intuit.com/replies/3300041
