I added a 2nd business in 2022, expenses all year, but my dba wasn't formed until October. Can I add this business to TurboTax along with my current sched c filing?

I had no income from this business, and paid everything out of my pocket.
1st, need to know it's OK to add business having expenses but no income, and 2nd, if it's OK that I've run the business all year but didn't get my dba until October. 
Ty!
