How can I stop the make tax digital popup without smashing my pc ?.

Hello there, paint-perfection,

The Making Digital Tax popup appears if no response is selected. If you don't need to set up MTD for now, you can select No for the prompt to disappear. You can always set up MTD once you're ready.

Check these article to set up MTD in QuickBooks:

Let me know if you have other concerns about QuickBooks, I'll be around to answer them for you.
