Is this normal for non-full year workers?

Here’s my info.

My W-2 wage was $11,906.05
Single Deduction $7,950.00(4,850+3,100)
Taxable Income $3,956.05
Federal Withhold $1,155.94

Tax from Tax Table $398

Refund $757.94 (1,155.94-398)

Does this look good to you?
Please help, I don’t want to have any trouble with IRS.

Thanks.

It seems pretty normal.
Don’t worry.
