It does not affect your GC processing, as you are legally working with authorized work permit (EAD) through TPS and your current status is TPS , not H4 (you reinstate your status to H4 only if you give up TPS or expire which does not seems logical as you started working with TPS EAD). So CoS to I-485 does not hamper if your current status is TPS. However, let your lawyer know that you are in TPS and used EAD so that she will not be confused with your TPS or H4 status.
