Turtle eggs are soft, I think they are even softer when it's the first 'batch'... Which does link to what steve said about first eggs don't usually make the healthiest of turtles. ^^"
Putting them under a heat lamp is usually a no-go because they can overheat easily like that, especially with no humidity and no temperature checks. If in the future you want to try taking care of them, I would suggest building an incubator (which is not that complicated to do, you can see some tutorials around, even videos) so you are ready.
An important thing in case you didn't know: Reptile eggs have a pouch of air that forms at the top after they are laid, and if your turn it the embryo will not be able to breathe anymore. It's a common things amongst breeders to draw a little cross at the top of each eggs so they know how to position them in the incubators!
And really, don't feel bad about it. Taking care of exotic pets can already be tricky, now taking care of exotic reptile eggs is another level! I know I would feel too intimidated when the time comes to even consider trying. ^^"
