This has nothing to do with a W-2.
No, I am not saying that you "should". You asked how to do it if you wanted to.
Yes, you have 2 choices;
1) As you said, report it now with a "mock" 2018 1099-R and ignore the real 1099-R when it comes a year form now, or
2) AMEND your 2017 tax return next year after receiver the 2018 1099-R. It does not go on your 2018 tax return since the earnings must be reported in the tax year that the contribution was made - 2017. (It would also be reported on your 2018 tax return *only* if the IRA custodian withheld any federal tax on the earnings which would be very unusual).
The 1099-R box 1 amount (total distribution including earnings) will be on 1040 line 15a, 1099-R box 2 amount (earnings) on line 15b.
Enter a 1099-R here:
Federal Taxes,
Wages & Income
I’ll choose what I work on (if that screen comes up),
Retirement Plans & Social Security,
IRA, 401(k), Pension Plan Withdrawals (1099-R).
OR Use the "Tools" menu (if online version under My Account) and then "Search Topics" for "1099-R" which will take you to the same place.
Be sure to choose which spouse the 1099-R is for if this is a joint tax return.
Be sure to pick the correct 1099-R type: Standard 1099-R, CSA-1099-R, CSF-1099-R, RRB-1099-R.
[NOTE: When you get to the "Your 1099-R Entries" screen where you can add another 1099-R, use "continue" to keep going as there are additional interview questions after that screen in most cases. You can always return as shown above.]
