That is one of the benefits of a deductible Traditional IRA. You get a deduction now for it and it grows tax deferred. You don't report buys, sell, interest, dividends or any transactions. So you can do a lot of stock trading and moving funds around inside the IRA.
You only report Distributions and rollovers and conversions. You will get a 1099R for those. You only pay tax on what you take out or convert to a ROTH IRA. But then it's taxed as ordinary income and not capital gains.
