We're sorry to hear that the instructions didn't print out for Form 8822 (Change of Address with IRS). You are correct that this particular document should be sent separately from your tax return. That said, your mailing address for sending Form 8822 to the IRS (from Alaska) is:
Department of the Treasury
Internal Revenue Service
Fresno, CA 93888-0023
You can confirm that for yourself by viewing Page 2 of a blank Form 8822 obtained from IRS.gov website at the following link:

Thank you for asking this question, and again we apologize for any inconvenience.
