Filing my 2019 Tax return error code 2123

I purchased turbotax 2019 today because im catching up on taxes (bad I know).

Im trying to netfile in it now and im getting code #2123, saying I claimed an employment insurance overpayment. This likely happened because I had switched jobs that year so I had two different employers.

How can I go about fixing this so I can netfile? I'd really prefer to not have to do this by snail mail.

many thanks!
