Part of the problem is that the IRS has greatly reduced the people working there this year. Retirees are not being replaced. Many federal employees are taking buyouts. Normally seasonal employees would be hired, but this year that did not happen.
They are receiving millions of returns and working with fewer employees, The delays are due to the IRS leaving returns in pending status for days now when they used to accept them within hours or minutes.
TurboTax is most affected because it has so many more users than other tax preparation software.
