I think I might’ve messed up on my application for an extension. It’s my first time filing, what do I do?

If you were able to submit your extension you should be fine. As long as the submitted date is before today you will be fine. If your extension gets rejected you will have a few extra days to resubmit. Then once accepted you will have until October 15th to finish filing your tax return.
