I have the same question. We (the parents) filed claiming our son as a dependent. We filed first, not knowing our son's precise income. Turns out he made just over the threshold to NOT be a dependent. His return was rejected since ours was already filed, so he changed his to conform to ours...not knowing that the stimulus payment hinged upon that. Now what do we do? Do we both file 1040X returns to amend? Will the IRS catch the mistake (based on his income being too high) and ask us to correct and refile? My understanding of the 1040X process is that it's entirely paper-based -- no e-file capability -- which takes 8 to 12 weeks to process. Will stimulus checks still be distributed by that point? Please help. Not sure what to do!
