What is T1M1 & T1F 2 YYYY YYYY XCSC?

[Lucero31]

My mom filed a I-130 for me, it's been 6 years now, we called so far 7 times in the past 3 months, only 6 show up on my portfolio. They say they sent a response, I have not received anything and they keep saying "call in a month if you don't receive it". It is sooooo frustrating!
Anybody knows what those T1M and T1F mean?
