Businessowner Now Employee

Used to be a small business owner, but business had been slow so decided to officially shut down business. Hired by a company in Jan 2024, closed business in March 2024. For the past 20 years, filed married jointly, using the Turbotax home+business software. To file 2024 taxes,  can we just use the home version only, and forget about the business? Btw, we had a loss in 2023 carried over. Also, with 2 W2s, we may owe the IRS. Several questions:

1. What software to use?

2. If filing married separately using home+business, how do we split the expenses such as home interest, etc.? Does the software know what to do? Thank you!
