Federal Tax Refund Delayed

Hello,

I filed early April 2021 using Turbo Tax. I am still waiting on my tax return. My best guess for reason for delay:

I had unemployment benefits for about 4 months in 2020 which I reported in the filing. Looks like the tax rules changed around the unemployment benefits - perhaps that is the source of delay? I am unclear if I qualify for the tax break on the benefits though given my income was high from the remaining ~8 months that I was employed. What are my options here? I have tried calling IRS a handful of times, but I get disconnected saying that they have high volume.

 

Thanks in advance!
