I received CP2000.
In 2008 I was enrolled in flex account and received $4000 after submitting daycare expenses receipts.
Total money I spent was $6900 on daycare in 2008. I did not report flex spending $4000 in the tax return.
I reported only $2900 which i spent above 4000.
Now Received CP 2000 asking about tax on $1100.
What should I do now? Do I need to refile taxes.
