According to information on p.839 of the Microchip datasheet for the PIC18LF56K42-I/PT (https://ww1.microchip.com/downloads/en/DeviceDoc/PIC18(L)F26-27-45-46-47-55-56-57K42-Data-Sheet-40001919G.pdf), the "PT" suffix indicates 48-lead TQFP package. The footprint you offer has a backside thermal contact (pin 49), but the package drawing for Microchip's 48-lead TQFP "Y8" package does not. Pin dimensions and locations are also slightly different than what's shown on the Microchip drawing. See http://ww1.microchip.com/downloads/en/DeviceDoc/48L_TQFP_7x7x1_0mm_Y8_C04-00300d.pdf.
