LLC and 1099 filing

Hello,

 

I started an LLC as a single owner sole proprietor in September 2019 and received minimal income and expenses through that business.

 

Most of my 1099 income and business-related expenses were through my personal for the year.

 

Do I report this income through the LLC? Can I write off those expenses through the LLC?  If so, do I also have to report this income and expenses on my personal federal return?

 

Thank you.
