One of my customers is an Intuit user and sent me a 1099 to my Intuit account. I cannot find the 1099 on my login.

Let me guide you on how you can log in to your account, Lily. 

You'll have to open the invite email and select the link so it will route you to your QuickBooks Self-employed account. Ask them to send the invite to the email address you used to sign in. If you don't have an account, you can create a limited QBSE account just for your forms. 

After that, you can now either fill out or update your W-9 or View your 1099-MISC. You can also check out this article for more details: Fill Out A W-9 and View Your 1099-MISC in QuickBooks Self-Employed.

Furthermore, you can check out our general guide for self-employed individuals, freelancers, and independent contractors to help you prepare your taxes. Go through this article for more details: QuickBooks Self-Employed Annual Tax Guide.

You can always let us know if you have any other concerns about 1099. We're here to help you. Have a nice day!
