You are able to contribute to your IRA until the filing deadline (April 18th this year). The IRA managers are given until May 24th to get Form 5498 out to you. To accommodate this the IRS allows you to file an extension, you, however, are responsible for any tax due by April 18th. To accomplish this, estimate the values of your IRA and fill in TurboTax and let it calculate the amount you owe (or refund) and mail a check to the IRS for the amount you think you owe. This will minimize you owing a lot of interest and or penalties. If you are getting a refund and need the money NOW, file your taxes, again, including the guess on the values you expect the Form 5498 and when the Form comes out in May then file an amended 1040 at that time and at least you will have gotten the Lionshare of your refund
