After you file

IRS did send a notice 3/2 (didn’t receive it yet but I spoke to IRS via phone call) and she said refund is on hold for 60 days because there could be errors and I should look through it for errors. I asked her what I should do if I notice the errors and she told me to amend it. So how can I amend it via turbo tax without turbo tax calculating having me already received my refund? Or do you think IRS meant for me to wait to amend after the 60 days? But if that’s the case why would she tell me to look through for errors if I have to wait 60 days for them to review everything and find the errors ?
