Retirement tax questions

Thanks for your response @DanaB27 !

 

Yes, this was excess contribution by employee. The total excess contribution was $1375. The plan administrator issued me a check of $1433.59 before Apr 15th deadline of last year. I think this included both excess and earnings.
 
I was expecting a straightforward 1099-R as I was able to take care of excess contribution in timely fashion, so I didn't pay attention earlier. But now I am stumped by the code E. 
In 1099-R, 
Box 1 is $1433.59
Box 2a is $1433.59 (same as Box 1 and includes everything)
Box 5 is $0.
Fed Tax withheld in Box 4 is $143.36
State Tax withheld in Box 14 is $14.34
 
I called the plan administrator but they told me to get in touch with the benefits department of my previous employer. I no longer work there so I don't know if I would get any response in time by Monday, Apr 15th. 
 
If I don't get a clarification, can I modify this 1099-R in TurboTax and file? If so, I will put the difference of $1433.59 & $1375 in Box 2a and $1375 in Box 5. Does this sound right?
