Where to deduct software expense such as QuickBooks and TurboTax

I was reviewing Section 179 deductions and noticed "software" was included. We are an LLC, taxed as a partnership. We use QuickBooks Online Plus as well as TurboTax. Is it correct to use Section 179 for the deduction, or should it be deducted as an Office expense?

I also saw where you do include sales tax in Section 179 deductions. Is this correct?

Thank you.
