After you file
Yes, that is how it should look. You originally claimed one child as a dependent and left the other child off the return. Now you are amending to add the second child, but as a nondependent (your ex will claim the dependency and Child Tax Credit for them). You won't be able to e-file, so the amendment is File By Mail. You should have an instruction sheet that list addresses and what to include.
When filing an amended or corrected return:
- Include copies of any forms and/or schedules that you're changing or didn't include with your original return. (include the 1040 and the 1040X)
- To avoid delays, file Form 1040-X only after you've filed your original return. Generally, for a credit or refund, you must file Form 1040-X within 3 years after the date you timely filed your original return or within 2 years after the date you paid the tax, whichever is later.
- Allow the IRS up to 16 weeks to process the amended return.
