I have just purchased new version of Desktop 2019. How do I get it ready for Making Tax Digital?

Thanks for contacting us here on Community.

If you have purchased the latest version QuickBooks Desktop 2019 and you are latest version you should be all set for MTD the release you need is R6P, you will be able to see this by pressing 'F2' or 'CTRL and 1' on your keyboard.

Please let us know if we can help with anything else.
