How do I deal with Personal Items in accounts?

How do I deal with Personal Items in accounts?

I switched my business to an LLC at the beginning of this year, and accordingly separated my personal accounts from business accounts.  Unfortunately, there were a few personal transactions that slipped through before I caught them so now they are showing up in my business accounts.  How should I categorize them so they are not included in my books, or can I delete them? Or, if I am to create an account labeled as "Personal" can I exclude it on reports?  Sorry for all the questions.

Please advise so it won't look bad on my reports.

Thanks so much!
