I followed the advice given to me through turbo tax and now I am having problems with my state, I believe according to the 100% guarantee please advise me

No one else can see your return so we have no idea what went wrong or what you think TurboTax did incorrectly.  TurboTax guarantees that the calculations will be done accurately.  But TurboTax has no way to know if the data you enter is accurate or complete.  Did the state send you a letter?

TurboTax does not receive any information from the IRS or your state after your return was filed, so no one at TurboTax knows about a letter you received from the IRS or the state.

(what the letters from the IRS mean)

TurboTax has a special phone number for help with IRS/state tax letters, which will be easier than going through regular Customer Support.   At the page below, click on the blue button that says "Get Help from TurboTax Support".  Then it will ask you what tax year is your letter.  Then it will ask you what the letter concerns. Then it will show you the phone number during posted business hours.
