Yes, you are correct. You will just need to input your W2 information for this year if you did not sell the vested RSU shares.
It will be critical though to keep track of the amount of the income that was taxed for the RSU shares, because that information will be needed at the time you do sell those shares. This income will be needed to determine the basis of the shares to help ensure that you aren't taxed again on income you already paid taxes on.
If you received dividends for the unvested shares, these will also appear on the W-2 as well. Once you own the shares, any dividends you receive will be reported on a Form 1099-DIV that will need to be reported on your tax return.
Here is more information about RSU Shares.
