Remember that you do not "log in" online to use 2018 desktop software when you are ready to prepare the 2018 return. You put the software on your own hard drive and use it by opening up the program on your computer. Your 2018 return will have to be printed, signed and mailed, since you missed the deadline to e-file.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS and/or your state received the return.
If you are getting a refund, there is no penalty for filing late. If you owe tax due, then file and pay the amount due as shown on the Form 1040, but expect a bill later from the IRS for the penalty and interest you will owe. Only the IRS will calculate this—TurboTax will not calculate it.
