How to get access to my last year 1099 (2018). I didn't accept the invitation last year and it is expired.

Hello there, @lopezmmv.

You'll want to contact the person who sent you the invitation and request an invitation again.

From there, ensure to accept the invitation to access your last year 1099. For more information about 1099 forms, you can check out this article: 1099s in QuickBooks Self-Employed.

Also, I've attached these Help Articles in case you have any other questions about e QuickBooks Self-Employee (QBSE).

Let me know if you have any other questions. It'll be my pleasure to help.
