Married Filing Jointly + Spouse with Small Business

Hello all,

 

My wife and I were just married in September and she started a small business and quit her full time job last year, and is currently a sole proprietor of the business. So this is our first year filing jointly, as well as our first year filing for her business. Can anyone advise how we do this? Which product would we use? Would the business side of it be separate, or does it all go into one filing? 

 

Anything dumbed down and step by step would be helpful for us, as we have no clue where to begin.

 

Thank you!
