How do I create a company file?

Welcome aboard to the Community, @j-sawilowsky3524.

In QuickBooks Self-Employed, one subscription is only equivalent to one company file. After getting a subscription, you can sign into the account using your login credentials and proceed with the setup.

Here's how:

1. Go to: https://selfemployed.intuit.com/.
2. Enter your username and password.
3. Follow on-screen instructions to set up the company.

If you're trying to create another one and want to use the same login information, I recommend buying additional subscription. You can follow these steps:

1. Visit our website: https://quickbooks.intuit.com/self-employed/.
2. Choose your subscription and select Buy now.
3. Press Yes, that's correct. 

For additional reference, check out the How to create an Intuita QuickBooks account article. It allows you to manage accounts easily and all of your Intuit products.
