ANSWER: 

If you prayed sunnah of fajr at home, you have to pray 2 rakahs when you enter the masjid, if you want to sit down. 

If you go and pray the sunnah in the masjid then it suffices for both. 

To pray Fajr sunnah raka’ahs at home and when get to the mosque then pray tahiyatul masjid before congregation. Is it right to pray between sunnah prayer and fard prayer? Or if I go to mosque & make intention to pray sunnah and tahiyatul masjid with one 2 raka’ahs?
