Hi Reymond, 

Thank you.

Sorry for insisting but I need to correct the amount that I have written off - the total amount a customer has to pay us was $ 3392 and for some reason, they paid only 1272, and they were unable to pay the remaining amount due to some complications, this all has happened in 2018. I have written off the remaining amount of 2120 last time on December 2019  believing that QuickBooks would save the date in which I have written off - what shall I do now? What is the best way to reverse this? And how can I write off as of year 2019? 

Also, I am not able to find the remaining amount that I have written off in the bad debt account, whereelse it could be located? Is this possible even?

Can you please walk me through this?

I am sorry for being silly.

Thank you so much

Meron
