If I entered the wrong amount in the Federal withheld box should I amend?

If you have filed the 2023 federal tax return, the IRS will probably catch the error for you.

Otherwise -

You will have to wait for the IRS to either Accept or Reject your filed federal tax return.
If the return is rejected you can make the necessary changes and e-file again.
If the return is accepted you will have to amend your original tax return. An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 20 weeks or longer to process an amended tax return.

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.

Maybe-----but not yet.  Wait for the IRS to fully process your return. They might catch the mistake and correct. it.   If they do not catch it then you can amend later.
