My tax return was rejected, twice. What do I need to do to fix it?

[karenjohnson0813]

It was rejected due to my dependent filed his taxes but forgot to check the 'someone else can claim me' box on his return.

You will have to print and mail your tax return leaving him as a dependent on your tax return.

He will have to amend his return to change his dependency.
