How many LAR entries did you have in 2020?
The reason I ask is to determine a percentage. Most likely, I would not resubmit for 2 entires. However, I would document the error, determine how/why they were not included in the 2020 LAR and the fix. If you do decide to resubmit, I would wait and make sure you have everything. You don’t want to resubmit and then have to resubmit again.
