Great, then in answer to your question ... the answer is "maybe". :(
The deduction is largely based on the LOWER of (1) Qualified Business Income (QBI) or (2) "taxable income" (adjusted for net capital gains, before the QBI deduction).
So the non-QBI rental would not affect Qualified Business Income. But it WOULD affect your "taxable income" (and could affect the adjustment for the net capital gain). So it depends on the rest of your tax return.
Do you have other income besides your freelance income? If so, about how much? What is your pre-QBI "taxable income" (Line 8a minus Line 9 of your Form 1040)?
The answer is Form 8995 (or 8995A, depending on your situation) because that is where the calculation is. Unfortunately, I don't think you can access that form on either H&R Block or TurboTax until AFTER you pay for the software.
