@xmasbaby0 is correct- it might be better to wait. You should always file with your current legal name as on file with the Social Security Administration on the date you sign the return.
However, if you will be increasing your tax with the amendment, it's a good idea to amend as soon as you can to stop interest accruing. You can ask the USPS to forward your mail, and update your address with the IRS using Form 8822.
