GSTR - 9 - Difference between Table 8C and Tabe 13.

Sir,

With reference to the filing of GSTR 9 for FY 17-18, I need clarification on the following issue.

If we have availed ITC for a bill pertaining to FY 17 -18 in FY 18 - 19 ( tru 3 B rtn. filed in that FY ), where should we mention that amount in GSTR 9, whether in Table 8 - C or in Table 13. Or both ? What is the difference between these two ( Table 8 - C and Table 13 ).

Please  clarify the above.

With Regards.
