If you haven't yet submitted your taxes, you can go back and make the correction in the Personal Info tab of your program.

If you have already submitted your taxes, as long as the child is listed with a correct social security number, you should have no problem.  I would not worry about amending or anything like that.

I sure hope so because I did just that

I just realized I put the wrong sex of dependent after my federal also state got accepted. How long do it take for next step.

If the IRS and State accepted your return, you shouldn't worry about it. You don't need to amend your return.
