I want to expand on this. 

The Section 83(b) election needs to be mailed to the IRS at the Service Center where you file your tax return within 30 days after the date the stock is transferred to you.    Hopefully you have done this.  If not, that is a problem.

In general, with restricted stock, it is not taxable until the year in which it becomes substantially vested.  With the 83(b) election you are making the election to include the value of this stock in your income NOW.  I would assume this income component is included in your W-2, and as such, you don't have to input this any where else.

In past years, making a Section 83(b) election prevented those individuals from being able to efile their tax returns since this form / election needed to be attached to the return (as well as mailed as explained above).  The IRS has recently eased their requirements here.  There are proposed regulations that apply to transfers of property after December 31, 2015 that a copy of the Section 83(b) election does not need to be attached with the taxpayers tax return. 

The preamble to the proposed regulations state that taxpayers may rely on the proposed regulations for property transfers after December 31, 2014. 

In summary, if you mailed a copy of the Section 83(b) election to the IRS Service Center within 30 days of receiving the stock, you can rely on the proposed regulations and do not also have to attach a copy of the election to your tax return.
