What is causing refund delays? Is it the 8915-e?

My refund has been “processing” for over two months now. I did not have any additional rebates or anything else that people are mentioning as causing delays. I did have form 8915-e this year. From what I’m reading, the IRS is actually getting pretty caught up so I do not understand what is going on here. People need these funds and it is impacting their lives.

 

Did anyone else file the 8915-e and experience the same?
