You just need to be patient with the IRS this year. All the letter means is that they are verifying your income and income tax withholding. This is not an audit and the IRS is verifying just about everyone that has EIC and Advanced Child Tax Credit.
Refunds are taking longer than normal. The 60 days is just an estimated time period, it could be in fewer than 60 days or it could be longer than 60 days. The 60 days is not up yet. My guess is you will hear something within the next week or so.
