Online tax preparation and e-filing for 2018 returns is now permanently closed. You had until midnight on Tuesday, October 15 to finish and attempt to e-file; if your e-file was rejected you had until October 20 to make corrections and re-file. Now it is too late to efile any return … they must be mailed in.

If you didn't already pay for your 2018 product prior to the shutdown, you can either purchase directly from the TurboTax website as mentioned above, or you may find the product at a discount as a download at Amazon, etc. CAUTION: There are a lot of scam sites, so do not try to purchase from any "too-good-to-be-true" discount site on the Internet that you find in a search. You might end up with pirated software, ID theft, malware, etc. Only a few large well-known sites like Amazon, NewEgg, Staples, Office Depot, etc., are authorized to sell TurboTax downloads.
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.

Don’t forget your state. And you will have to print and mail your returns. So be sure to attach copies of your W2s and any 1099s that have withholding on them. You have to mail federal and state in separate envelopes because they go to different places. Get a tracking number from the post office when you mail them for proof of filing.
