GST Input 2017-18

I have taken and  utilised input credit in the month of March 2018 based on the bills received from registered dealer. But the credit appeared in 2A in the month of Sept 2018 ( vendor uploaded GSTR1 late as permitted by GST department).  Is this is eligible for the year 2017-18 as credit appeared in 2A of 2018-19 (Sept 2018).

Kindly request for your valuable advise on the above with supporting notifications if any.

Thanks and Regards
