If you are self employed, and the landlord wants a PNL that is certified by an accountant, then you have to find an accountant to prepare one for you, or find another apartment to rent. This is not an income tax issue.
If your business was active in 2023, your 2023 tax return will report your gross income, expenses and profit on schedule C. You can show the landlord your tax return, but if they want to see an accountant's signature, there is nothing Turbotax can do, you need to find an accountant to work with you.
If this is a new business, and you are using business accounting software such as Quickbooks, the software can generate a PNL statement for the quarter or the year to date. But it won't be signed by an accountant unless you pay an accountant. This is not a tax problem, your problem is your future landlord is being very careful or very picky.
