The status in the image you posted is "started." That means the return was not finished and filed. There's no evidence in that image that the return was efiled.
If the PDF has your finished return, you can print it and review it. If all is in order, you can print, date, sign, and mail it to the IRS using any instructions in your CP59 letter. However, if anything needs to be finished or changed, you'll need 2017 desktop software. Then you can download the *.tax2017 data file, open it and finish it in desktop software. If you have already paid for 2017 back then, you can speak to TurboTax Support to request a free download of the software.
The 2017 return cannot be efiled with TurboTax. It has to be printed, signed, dated, and mailed.
What about the 2017 NY state return? Did you mail it to NY last year? If it hasn't been filed, then that will be another task.
If you need to reach the folks at TurboTax Support, such as for the 2017 software or further assistance, here's how to contact them during business hours:
