After you file

This situation also happened to me.  My husband and I both got letter 6475.  His was correct- he received $700.  Mine said I received a check for $3500 but my check was $1400 (I received no additional checks).  I understand that now I have to fill out the form for a trace?  And send it in to the wild blue yonder and wait for how long???   So in the meantime I have to complete my taxes stating that I received a $3500 check when in fact I received a $1400 check... just because that is what this letter states?  I thought the IRS does not want you to falsify your tax return?  I still have the check bc I deposited it electronically.
