I made an error when completing form 11 for 2018 and I amended it the following day but discovered that I made another error on the amended form - in the column tax paid directly to the Collector General i put in the amount of preliminary tax I was going to pay in October 2019 not what I paid in October 2018. I got an acknowledgement Notice of Amended Assessment for the first form but have heard nothing about the second amendment. Do I need to contact Revenue or should I wait and see if they come back to me in due course.
