Retirement tax questions

No.  Losses in an IRA are not deductible.

If you deducted the contribution when contributed then the distribution is taxable now since you did not pay tax on the money then.

If it was a non-deductible contribution then it would be a "basis" in the IRA that would offset the tax assuming that you had no other Traditional, SEP or SIMPLE  IRA accounts at the end of 2018.
