Do I enter business expense with tax collected or without

[Glendag]

And where do I put Texas Sales and Use Tax Payments in Turbo Tax?

[CherylW]

You can do it one of two ways: 

1.)  Report the sales net of sales tax as income on Schedule C, or 

2.)  Report the sales with tax added to it (sales + tax = gross sales) on Schedule C, and then take the sales tax paid as a deduction under Taxes Paid (that's where you'll put your Texas Sales and Use Tax Payments) in the expense section.
