My wife and I have a business together. We have several 1099's to file. How does it allow us to seperate

[NancyG]

Set up two separate businesses, one for each of you.

For 1099-Misc forms that you want to split: 

You will enter the 1099-Misc twice, each time using only the amount you want to go to each specific business. 

To add multiple IRS Schedule Cs:

• go to Business tab; then Continue
• choose Explore on my own or I'll choose what to work on  (if it comes up)
• then Business Income and Expenses
• then Profit or Loss from Business, click Start or Update.  
• you should see the Business Summary page that lists your businesses, 
• right below the list you can Add Another Business.
