If you rolled over a 401k, you need to have from 1099-R from the 401k administrator. Is Fidelity where the money came from, or where it went? Was it in 2016? Those form 5498s only report year-end balances and contributions made. When you get form 1099-R, enter it here (rollovers are tax-free but still reported):
Click Federal Taxes (top menu)
Click Wages & Income (just below top menu)
Scroll down to Retirement Plans and Social Security and click Show More (if necessary)
Click Start next to IRA, 401(k), Pension Plan Withdrawals (1099-R)
Enter your 1099-R exactly as printed, paying special attention the the distribution code in Box 7 and the "IRA/SEP/SIMPLE" box.
