I paid you guys to do my taxes alst year but you couldnt complete them. do i have to pay you again to try to file for the 2019 taxes?

Not sure what you mean by "you couldn't complete them."   What happened?  Why was your 2019 tax return not filed?   Was it rejected?   Most rejections are for AGI---which no longer matters since you only need that to e-file.   A 2019 return cannot be e-filed----it has to be printed, signed and mailed now.

Or was something else wrong?   

Online tax preparation and e-filing for 2019 returns is now permanently closed.  You had until midnight on Thursday, October 15, 2020 to finish and attempt to e-file; if your e-file was rejected you had until October 31, 2020 to make corrections and re-file. Now it is too late to use online software or to e-file. If you have any changes/corrections at all to make to your 2019 return, you now have to complete it using desktop software, which you must download to a full PC or Mac  (not to a mobile device).Then you need to print, sign and mail it.

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.
