Yes.

Hello my tax refund it's 1000 but Total Payments/Credits it's 2000 dollars no I have to pay it 

Just to clarify, what do you mean by my tax refund is 1,000 but Total payment/ Credits is 2,000. Where exactly is that showing in your Turbotax program?

Just want to know what's Total Payments/Credits

Payments are any withholding from your W2 or 1099 forms or estimated payments you paid.  Credits would be like the Child Tax Credit one Earned Income Credit.  Those are deducted from the total tax on all your income giving you a refund or a tax due if your payments weren't enough to cover the tax on your income.
