Since your 2017 return was already filed and accepted by the IRS, you flat out can NOT e-file another 2017 return. Period. To report the additional income you will need to file an amended return. Now since you filed your original return with H&RB, using TurboTax to file an amended return will be *expensive* and complicated. I suggest you return to the entity that filed your original return and have them amend your already filed tax return for you.
Note also that *you* can not e-file an amended return. The IRS says so. You would have to print it, sign it and mail it to the IRS.
