in the $ECP group and in the $DATA group. The correct name for this ECP and basis set is SBKJC

In addition, $BASIS group and basis sets given for each atom in the $DATA group are contradictory. If you give basis set for each atom individually (which is necessary when you use ECP only for selected atoms), you don't have to give $BASIS group. And if you want to use polarization and diffuse functions, the correct input for 6-311+G** is like this:

C           6.0   1.7128704695  -1.2666889192  -0.1389832102

D   1

P   1

The exponents for polarization and diffuse functions are taken from https://bse.pnl.gov/bse/portal. Note the blank lines separating input lines for each atom. These blank lines should be between atoms and between the last atom and $END of the $DATA group.
