Welcome to the Community, @KINDsoap.
Let me help and provide insight about bills showing up on the 1099 report in QuickBooks Online (QBO).
To start, make sure the mapping is correct in the expense account of the transaction so only those entries for 1099 will show in the report. You can check this article to help you troubleshoot missing contractors or wrong amounts on 1099s.
Regarding your question about deleting bills, if the bill isn't included in the report, you can delete it. However, I recommend consulting your accountant for guidance as it may be linked to payments.
For future reference, you can check this article to guide you in customizing your reports and focus on the details that matter the most to you: Customize reports in QuickBooks Online.
Don't hesitate to leave a comment below if you have follow-up questions about bills, 1099, or other QBO-related concerns. I will answer them in any possible way.
