If you are an Injured Spouse with a Form 8379 for the return used to calculate your stimulus check and your portion was withheld, you don't need to do anything just yet. The IRS is reissuing the Injured Spouse's share of the stimulus check if it was erroneously withheld. If you have not received a check for the portion attributable to you by the end of August, you can call the TAS.

If, after you submit the form, you have not received a check for the portion attributable to you by the end of August, you can call the TAS.
