tlapanne, after reading all the comments and sugestions above, my recommendation would be to settle with the IRS -- explain that because of the change of jobs, time etc. you do not have the records to prove the claims -- show them what you have and go on from there. Throw yourself at the mercy of the IRS and hopefully you can get some kindness from the auditor. I am sorry for your situation, but there is not much you can do about it other than accept and move on. And yes this does mean that chances of future audits of your returns may go up a bit. Still very few people get audited.
As for the future, please recognize that TurboTax , like all the other tax preparation software , does a very good job of helping you prepare your taxes but it cannot replace human preparer. It does use all the data that you provide and fills out the forms and transmits the data to the tax authorities. Also note that whether you use tax software or a professional to prepare your return, you still remain liable for evrything on that return -- there is no way to escape that. With that proviso, you should be fine preparing your own returns with TurboTax ( or any other tax-prep software). Good Luck
