Filing taxes on stocks
You need to talk to an accountant who practices tax accounting, preferaby someone who is an Enrolled Agent (EA) with the IRS, and possibly an attorney who specializes in tax law.  There are multiple issues here, and the executor of your father's estate might need to be involved here too.  Presumably you were a minor in 2007 since the transactions took place in a custodial account, and perhaps you were a dependent of your father in 2007.  So, were the transactions reported on your father's 2007 income tax return? or did he file a separate income tax return in your name? You say you have a W2 for 2007. So you were  earning some income in 2007? This complicates matters. It is necessary to determine who has the responsibility to file income tax returns for a minor with earned income. Above all, I urge you to not file income tax returns on your own or using a tax return preparation program, or after talking to a tax return preparation service (where you will likely get someone who works on a seasonal basis and is unlikely to be familiar with tax law as of 2007).
