I sent and injured spouse form by mail after we efiled so how and when will i know if its accepted?

The IRS will notify you by mail.  According to the IRS instructions for Form 8379 - Injured Spouse Allocation:

Generally, if you file Form 8379 with a joint return on paper, the time needed to process it is about 14 weeks (11 weeks if filed electronically). If you file Form 8379 by itself after a joint return has been processed, the time needed is about 8 weeks.
