Retirement tax questions

My wife was caught with a change of jobs and slightly over contributed to her 401k(s).  And turbo tax does have the mistaken information I was going on to withdraw the excess.  I was told 4/15 by the 401k administrator as well but had been relying on Turbo Taxes' information.  Its a hyper link that you can click on to pop up more information when it goes to check your retirement contributions and contains steps to take to make the correction before 5/17.  I thought we had plenty of time, at least until the new tax deadline as well because of this information.  To my disappointment the 401k administrator is correct with 4/15.  This does make me wonder what else Turbo Tax may have incorrect in their software??  I've use them for 30+ years too.  I was hoping to reach them directly but can't find a direct contact method.
