Cudo, are you asking what that chord is, or are you asking how to enter it into BIAB?

In BIAB, you type Cmaj7#5. Without the "j" it won't work. And no parentheses.

Also, check out the chord builder function by right-clicking, chord builder. This shows all supported chord types and, more important, how they must be entered in BIAB.
