Retirement tax questions

Opened the TT program and there was an update but, guess what, no change when it comes to lines 4a and 4b.  I understand that some people are getting the correct refund even though line 4a is less than 4b but some are not and then they have to contact the IRS and file an amendment.  Why can't this be fixed so that there won't be problems for anyone who is dealing with line 4a being less than 4b? I am disappointed and frustrated that nothing is being done.   :(    :(  I am holding off filing because of this especially since I talked to an IRS agent who told me that line 4a of my form needs to include all of my distributions.
